TO ALL WHOM IT MAY OONOERN:

Be it known that I, HORACE REsLEY, of Cumberland, in the county ofAlleghany, and State of Maryland, have invented certain new and usefulImprovements in Self-Connecting and Detaching Oar-Couplings; and I dohereby declare the following to be a full, clear, and exact descriptionof the same, reference being had to the accompanying drawings, making apart of this specification, in which.- v

Figure l represents in perspective one ofthe coupling-boxes, with thecoupling-link or bar in position in it.

Figure 2 represents a horizontal section through the same. Y

Figure 3 represents a view of the end of' the coupling-link or har,showing the hevelled form thereof.

Similar letters of reference, where they occur in the separate figures,denote like parts in all ofthe drawings.

My invention relates to that kind of self-acting car-couplings in whichthe coupling-link or bar, in connecting or disconnect-ing itself` fromthe adjacent cars, has a rolling motion around its long axis, as will beexplained.

To enable others skilled in the art to make and use my invention, I willproceed to describe the same with reference to the drawings.

The coupling-link or har A may be straight, as shown by the black lines,or of a goose-neck form, as shown by the blue lines in iig. 2; and itsheads are made with shoulders, a a, so as to catch and draw upon bothsides of the head. The ends of the link or bar A are so bevelled otf, asat b, iig. 3, as that, when they strike against the Haring portion ofthe hex or head B, it will rock or rollin the line of its length, andvthe narrow E l part of said end freely enter the opening in the box B,and then roll or rock bnckngan, sol that the shouldersl a shall take andhold against the sides or shoulders c c of the box. For the sake ofconvenience, and to prevent rattling, or, possibly, the dropping out ofthe link or bar A, I propose to suspend it to the box B hy a hingedmetal strap, (Z, with holes, e, in it, to a pin or stud, j', in the boxB; and a cord, g, is connected to the link or bar A, by which said baror link may be slightly turned, to disconnect it from the box. Theentire series of links or bars throughout the train may have their cordsconnected to a common cord, chain, rod, or other contrivanee, so thatthe whole series may be uncoupled at once, or by one operation. Thepurpose of the goose neck formed link or har is to adapt the coupling tocars whose platforms may vary somewhat in height; or these links or barsmay he swivellcd at er near their centres, so that one end of it onlymay rock or roll to disconnect that end, leaving the other connected tothe box. The rear of the box has an opening, 7i, through it for the rod,by which the box is attached to the car, or the latter drawn by, to passthrough, and a recess, i',

also, for the head of the bar, so that it need not enter into the box B,and occupy space therein. The corners of the box, as at j, are maderounding, to conform to the rounded form of the ends of the link or bar,so that Lw the latter may move and not bind therein, but, at the Vsainetime, be prevented, by the motion of thc train, from too much rattlingmotion. v

When the link or bar A is in the position for entering thehead or ofleavingit it rcprcsents'an appear. ance like that shown by red lines iniig. 2, and quite narrow. By drawing from the two sides of the box, thotendency of the draught in going around a curve is to prevent the outerwheels from climbing the rails.

By my construction of couplings, the engineer may disconnect thc cars ofthe train from each` other, or from the engine, at will. v

What I claim, and desire to secure hy Letters Patent, 1s-

1. The links or bars A, with shouldered heads and hcvellcd ends, andsuspended by a flexible connection, so that they can rock or turn in theline of their length when they are to connect ordiseonnect the train,substantially as described.

2. I alsoclaim, in combination with the link or bar A, c

.f' box B, with shoulders c c and rounded end j,

onstructcd and operating as above described, the as and for the purposeherein described and represented. i
